Hi all, 1. If a mail is temporarily deferred from a remote MTA, postfix should back-off instantly for some time but I observed this today. Jul 24 06:40:16 server.name postfix-smtp4/smtp[6204]: DEC8B4F0185: host mta6.am0.yahoodns.net[98.138.112.35] refused to talk to me: 421 4.7.0 [GL01] Message

Abhijeet Rastogi: The issue is, why does postfix retry the second time instantly (within 1 sec)? Shouldn't postfix wait till the next deferred queue scan happens? No, this is not required. If you disagree, please point out in the SMTP standard, RTFM RFC 5321, where Postfix is in error.
